Ecological condition measure Assessment grade Confidence
Very poor Poor Good Very good In state grade In trend grade
AUSRIVAS O:E score Improving Adequate high-quality evidence and high level of consensus Adequate high-quality evidence and high level of consensus

AUSRIVAS = Australian River Assessment System
Notes:
1 See Table 6.4 for the AUSRIVAS Observed:Expected (O:E) score band descriptions.
2. State of the ecological condition is based on the percentage of sites with an OE score of A or X. Very good = 76–100%; Good = 51–75%; Poor = 26–50%; Very poor = 0–25%. Trends classified as improving (up arrow) or declining (down arrow) = if there has been a 5% or greater change in the frequency guideline levels are exceeded relative to 2007–2011. The overall ecological condition score (in bold) is the average of all measures. Overall score is the average of all ecological condition grades.
